CHRQMATlC-PRINTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 263,762, datedSeptember 5, 1882.

Application iiled"February 23, 1882. (No model.)

To all whom it may concern Be it known that l, EDGAR H. GAUGHEY, acitizen ot' the United States, a resident oi' Erie, in the county otErieand State of Pennsylvania, have invented new and useful Improvements inUhromatic-Priuting Apparatus; aud- 1 do hereby declare that thefollowing is a full,

clear, and exact description thereof', reference `in any ordinaryprinting-press in connection with ordinary type, and will make chromaticimpressions while the type are making common black impressions.

My device `is shown in the accompanying drawings as follows, the viewsbeing exag-l gerated:

Figure 1 is a top view of the device com` plete. Fig. 2 is alongitudinal sectional viewV on thelineyyin Fig. l. Fig. 3 is atransverse sectional view on the line .r x in Fig. 1. Fig.

4 is a perspective view of the device with the` upper plate removed.Figs. 5 and G are details ot'lconstruction.

A is the body of the apparatus. VB is the upper or face p1ate (l, thelower plate or back.

F, for receiving the mechanism for operating `ot' theplate may bear anyother engraving desired.

In the face-plate there are openings d e, which are for the admission ofink to the wells Dand E. These latter openings are closed byspring-valves. (Shown by dotted lines in Fig. l.)

The .pressure-plates G G set a little above the face-plate B; but whenthe type is under pressure in the press thc plates are pressed down evenwith the surface of the plate. When this occurs the color-type T T areraised by the mechanism contained in the apparatus, and make a coloredimpression at the same time that the ordinary impression is made. Thismechanism is as follows: Connected withV each pressure-plate is aplunger-rod, l, which connects with levers 2 2, which are pivoted at 4,and are connected at their inner ends with an equaliziug-bcam, 3, whichis pivoted to the the central type, which in this case is a star; andalso attached to rod 6 is a beam, 5, which extends longitudinally iu thelower cavity, F, and carries at its ends the plunger-rods 7 7, to whichare attached the end type. The arrangement of this mechanism is suchthat it' one of the pressure-plates G only is pressed down neither ofthe plnngers 6 7 7 is raised, for the equalizing block or beam 3 will hetilted, and thus take up the movement; but if both pressureplates aredepressed at once the equalizingbeam is raised bodily, and hence arealso raised the plungers 6 7 7. The object ot' this movement is this:When the inkingroller of the press passes over the type it will y onlybe in contact with one pressure-plate at a time, as it is of smalldiameter, and consequently the color-type will not be raised; but whenthe impression-cylinder or the impression-plate ot' the press comes uponthe form both pressure-plates G G are subjected to an `equal pressure,and the color-type are raised through their openings in the plate B andbrought into contact with the paper.

The color-type are made as follows: A skeleton of wire is formed with astem, t, by which the letter can be clampled and held in place. (SeeFig. 4.) Upon this skeleton 'is attached a body of brous material whichhas its ends plunger-rod (i, which carries on its upper end IOO orshreds left hanging below. (See Fig. 6.) The fibrous material is packedsolidly together on the frame and forms a face for the type, and theshreds which drop down enter the ink contained in the ink-wells and drawit up by capillary attraction and keep the face of the types inked. Theornamental type in the center (the star) is made in the same way. y

When a line of letters occur, as the words Erie anti City 7 in thedrawings, the colorletters T are clamped onto a single bar, 8, by theirstems, and are thus all moved at once by a single plunger-rod. The stemt ot' each letter is provided with a shoulder, J, which sets upon thebar S, to which they are clamped so as to give the letters a uniformheight. The type operated from the central plunger, 6, may be anornamental figure, as shown, or a line of letters or other signs ordesigns. The twoinkwells D and E allow ot' two separate colors beingused, and they may be divided so as to permit of more colors being used.

When the apparatus, as a whole, is set in a forni of type it should beso placed that the inking-roller shall pass over it from side to sideand not from end to end, so as not to come in contact with bothpresser-plates at the same time.

Where the letter-openings through the plate are of such form that a parthas to be sustained independently-as, for instance, the center of an 0or the space in the upper part of an R, as shown in the drawings-a bar(shown by dotted lines in Fig. 1) is soldered on underneath the plate Band the skeleton frame of the letters T, the fringe of the ber 4 otherpurposes.

forming the body of' the letters T being parted over said bar.

The plungers 1 1 are kept up when the pressure-plateis not underpressure by leaf-springs J J, the ends of which are seen in Fig. 3, audin Fig. 2 one is shown mostly by dotted lines. Springs for this purposemay, however, be located at other points-as, for example, a coilspringmay be placed in the passage in which the plungers 1 operate.

My apparatus as a whole may be used in the columns of a newspaper-form,and will print chromatic impressions at the same time thc blackimpression is printed. It may be used separately for printing labels andfor various Of course the primary inkthat is, the ink put on by thehiking-rollermay be of any color desired, and the ink-wells in the typewill supply the other colors. 1f there is only one ink-well, then onlyone other color will be supplied; if two, as shown, then two othercolors will be supplied, and so on.

What I claim as new is- 1'. A chromatic-printing apparatus consistingessentially of the combination of the following elements: a bodyhavingtherein one or more ink-wells, a face cap or plate covering the same, inwhich are openings into the ink well or wells of the form of the designto be printed, type formed of absorbent material mounted in saidopenings and extending into theinkwellorwells,and,tnally,pressureplatesworking in slots in the face ofthe body-plate, and which areconnectedwith mechanism, substantially as shown, whereby when the saidprinting apparatus, as a whole, is under pressure the said type formedof absorbent material will be raised from the ink well or wells apdlpressed against material being printed.

2. In a chromatic-printing apparatus, the combination, substantially asdescribed,of the following elements: a body, A, having one or moreink-Wells on its upper side, and acavity, F, underneath the wells forthe reception of actuating mechanism, a face-plate, B, withchromatic-type openings, a plate, C, covering the back of the body,absorbent type arranged substantially as shown, and connected byplungers with the mechanism in cavity F, and pressure-plates Gr G at thesides of the faceplate, which arealso connected with the mechanism incavity F.

3. In a chromatic-printing apparatus, the combination, substantially asshown, of the following elements: the presser-plates G G, plungers 1 1,levers 2 2, equalizing-beam 3, bar 5; and plungers 6, 7, and 7, and themovable type T T.

4. In an apparatus for printing in various colors, the combination, witha stationary faceplate of type, the designs of which lie below thesurface ot' said tace-plate, said type resting upon levers operated bypressure-plates having their faces above the stationary face and workingin slots therein.

In testimony that I claimthe foregoing I have hereunto set my hand this4th day of January, 1882.
